HENRY ADLER, OF ALLEGHENY, PENNSYLVANIA.

GAS-HEATER.

SPECIFICATION forming part of Letters Patent No. 633,061, dated September 12, 1899.

A Application filed August 12,1397. Serial No. 647,980. (No model.)

To a, whrmt it ntrty concern-.-

Be it known that I, HENRY ADLER, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pen nsylvania, have invented a new and useful Improvement in Gas-Heaters; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to gas burners or heatcrs. Y

The object of my invention is to provide a burner for burning gaseous fuel which is neat in appearance to the eye and can be easily and cheaply constructed.

Another object of my invention is to provide such a burner in which proper and complete combustion can be obtained by the mixture of gas and air thereto, so as to obtain as great a heating power as possible and at the same time prevent the entrance of gaseous or obnoxious vapors into the apartment in which it is used.

A still further object of myinvention is to provide a burner having a most powerful radiant heat and the utilization of as much of the waste heat as possible before it passes into the flue.

My invention consists, generally stated, in the novel constr uction,arran gement, and combination of parts, as hereinafter more specifically set forth and described and particularly pointed out in the claims.

To enable others skilled in the art to which my invention appertains to construct and use the burner, I will describe the same morefully, referring to the accompanying drawings, in which Figure 1 is a front or plan View of my improved burner, showing the same applied to gas-stove. Fig. 2 is a vertical central section of the same on the line 2 2, Fig. 1. Fig. 3 is an enlarged vertical section of a portion of the burner; and Fig. 41s an enlarged cross-section of a portion of the burneron the line 44, Fig. 3.

Like letters herein indicate like parts in each of the figures of the drawings.

My improved burner A for burning gaseous fuel is shown as applied to a gas-stove B,which is formed of sheet metal and is of the same general construction as that shown and described in an application filed by me on J anuary G, 1897, Serial No. 618,140; but it is evident that the burner can be applied to any form of stove, gas-heater, or fireplace, if desired.

The burner A is preferably formed of sheet metal, although any suitable material can be used without departing from the spirit of the invention.

The burner Ais preferably made from two pieces of sheet metal forming the front piece a and back piece I) with the chamber 0 between them and are held together by means of the lap edge (Z on the back piece I) bent over the edges of the front piece a. The front piece Ct has its front face a bent to form a series of steps or step-like projections a which form the horizontal or straight faces 6 and the up wardly-extending portions f, which are inclined forwardly from the chamber 0 and back piece I). A number of small holes or openings g are formed in the horizontal portions e for the escape of the gas from the chamber 0, and asbestos fiber h is secured-over the upwardly-extending portionsf in any suitable manner for the gas to strike against directly as it escapes from the openings g. The air and gas mixer 71 is secured to the lower end of the back piece I) in the rear of the burner A and communicates with the chamber 0 of the burner A through the openingj, formed in the back piece b.

The stove B shown is particularly designed for the burner A, and consists of the back 70, sides 7t, and front panels all formed from one piece of sheet metal and bent to shape,

over which is secured the top piece I, which is provided with the openings Z therein for the escape of the heated air into the apart ment. A front base-piece m is secured to the front panels 70 of the stove B, which is bent to suitable shape and is provided with a seat m on the top edge thereof for the reception of a fender at, having a handle n thereon, which rests against the front face a of the burner A.

The burner A is secured or held within the stove by means of braces 0, secured at or near the bottom of the burner A on the rear or back piece I), and the upper part of the burner A is held in place by a bent flange p, engaging with the top edge of the burner A over the lap edge d thereof. The bent flange 1) forms part of the bottom 19' ofthe chamberp for the escape of the products of combustion, which is provided with a top 19 terminating in a hood q, extending out in front of the stove B and secured thereto. The back 19 of the chamber 19 is secured to the back 7t by means of bent flanges p, engaging with an escapeopening a", formed in the back 70, which leads into the escape-flue r, fitting within a collar r secured to the back 7t of the stove B.

The stove B is provided with the gas-chamber s in front of the burner A and an airheating chamber 8 between the burnerA and the back 76, which communicates with the flues 8 secured between the bottom platep and top plate 19 of the chamber 19 for carrying the heated air out through the openings Z in the top plate Z into the apartment. Airopenings t are formed in the back It and sides k of the stove B, and a gas-supply pipe u enters one of the air-openings t in the sides and connects with the mixer 2' on the burner. The operation of my improved gas burner or heater is as follows: Gas being supplied to the gas-pipe u will enter the mixer 2', which is supplied with air from the air-openings i, and the mixed gas and air will pass from the mixer 71 into the chamber 0 of the burner A through the opening j and out through the openings g in the horizontal faces 6, where it is ignited by any suitable means. The flame or ignited gas and air as it passes out through the openings g in the horizontal faces 6 will strike directly against the asbestos fiber 72 on the upwardly-extending portions f and pass up in the gas-chamber s over the step-like projections a on the front face a of the burnerAintothe chamberp, around the tines s and out through the escape-flue r into the open air or chimney-flue, as desired. The heat from the flame on the face a of the burner A will pass into the apartment from the gaschamber 8 below the hood g, and the heat will also be radiated into the apartment by the waste gases striking against the top 19 of a the chamber 1) and radiating therefrom through the openings Z in the top piece Zof the stove B during the passing of the gases from the gas-chamber 8 through the chamber 19 into the flue r. The heat from the burner A will warm the air in the heating-chamber 3, fed thereto from the openings 2f, which will pass up through the fines s and out through the openings l in the top plate Z into the apartment.

Itwill thus be seen that my improved gas burner and heater is cheap and simple in its construction, containsfew parts, and will give great heat therefrom. On account of the peculiar construction of the burner the flame will be a continuous and solid mass over the front face of the burner, which will be pleasing to the eye on account of theincandescent effect of such flame on the fiber and face of the burner caused by the action of the flame directly against thefiber and face of the.

burner.

Various modifications in the construction and design of the various parts may be resorted to without departing from the spirit of the invention or sacrificing any of its ad vantagesu What I claim as my invention, and desire to secure by Letters Patent, is

l. A gas burner or heater composed of a chamber having a face com posed of a series of steps or step-like projections, the up wardly-extending portions of which are inclined forwardly, and there being burner-out-' lets in the horizontal portions of said steps or projections, adapted to direct the gases against the inclined portions thereab0ve,substantially as described.

2. A gas burner or heater, composed of a chamber having a face composed of a series of steps or step-like projections, the upwardly-extending port-ions of which are inclined forwardly, asbestos fiber or other incandescent material on the upwardly-extending portions, and there being burner-outlets in the horizontal portions of said steps or projections, adapted to direct the gas against the incandescent material on the inclined portions thereabove, substantially as described;

3. Agas-burner comprising a substantially vertical face having upwardly and forwardly inclined portions provided with asbestosor other incandescent material and substantially horizontal projections having jet-orifices so disposed as to direct the gases againstthe asbestos-covered surfaces.

4. A gas-burner comprising a substantially vertical face, said face having upwardly and forwardly inclined portions provided with as- HENRY ADLER.
